Hill Street Blues

Great TV show theme songs have a tendency to sneak up on you when you least expect it. Often times, you'll find yourself humming one while taking a shower or walking down the street – and soon enough it'll be stuck in your head for the entire rest of the day!

But that's what makes a theme great. It worms its way into your brain and stays there for as long as you can remember, just like a decent Top 40 hit. Sometimes, if it's good enough, it'll even stick around after a show has ended.
